If your ESC is alright an external BEC is another option you could try instead of replacing your stock ESC , then your ESC is supplying power for the motor only.
Either a Yep or CC ESC would work ,I believe most use the CC Ice lite 50a with good results and now its superseded you may be able to pick one up cheeper!
The 12t will give you better flight time for sure and if your interested in a Bec I'll let you know how mine goes when I get it , install it and try it out.
KX is using stock Esc (I believe),H450, mg servos with an external Bec you could ask him how's its going?
+1 to that

Check your gear mesh. Otherwise, you'll get a higher whine out of the main motor (the screaming sound of ampdraw), and both it and the ESC will overheat, and can eventually burn them both to death from the high temps. Magnets do not love heat - BL or not, they do not recover from heat damage. Circuit boards hate heat also. Improper gear mesh will also kill the bearings in the motor, and if it's tighter, then it'll chew up the main gear as well. check that stuff out hoss!
